Hi, I'm try to wrap the eggtrayicon like in the tutorial at this page: http://www.ibm.com/developerworks/linux/library/l-wrap/
The tutorial il very old, but It's better than the faq, so I have a problem:
I generate with h2defs and eggtrayicon.h the trayicon.defs file
I wrote a trayicon.override
I wrote a simple Makefile to generate the trayicon.c
Now I encounter this error:
pygobject-codegen-2.0 --prefix trayicon\
--register `pkg-config --variable=defsdir pygtk-2.0`/gdk-types.defs \
--register `pkg-config --variable=defsdir pygtk-2.0`/gtk-types.defs \
--override trayicon.override \
trayicon.defs > trayicon.c
Could not write getter for GdkDevice.axes: No ArgType for GdkDeviceAxis*
Could not write getter for GdkDevice.keys: No ArgType for GdkDeviceKey*
Could not write getter for GdkDragContext.targets: No ArgType for GList*
Could not write getter for GdkDrawable.handle: No ArgType for gulong*
